MONITORING HEALTH POLICY COMPLIANCE FOR PROTECTING CONSUMERS HEALTH AGAINST CONTAGIOUS INFECTIOUS DISEASES WHEN USING PRODUCT VENDING MACHINES

Abstract

A product vending machine comprising a monitoring system designed to monitor whether consumers in a consumer area of the product vending machine comply with one or more stored health policies for protecting consumers' health against contagious infectious diseases and containing recommendations on one or more of interpersonal distance, body temperature and use of respiratory personal protective equipment. If one or more consumers in the consumer area of the product vending machine are determined to fail to comply with the stored health policies, the monitoring system is further designed to implement one or both of informing the consumers in the consumer area of the product vending machine that one or more of the stored health policies fail to be complied with by one or more of the consumers in the consumer area of the product vending machine, and modify operation of the product vending machine so as to cause the consumers in the consumer area of the product vending machine to become aware that one or more of the stored health policies fail to be complied with by one or more of the consumers in the consumer area of the product vending machine.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims priority to European patent application no. 20206010.9 filed on 5 Nov. 2020 and Italian patent application no. 102021000027371 filed on 25.10.2021.

TECHNICAL FIELD OF THE INVENTION

The present invention relates in general to product vending machines, and in particular to monitoring health policy compliance for protecting consumers' health against contagious infectious diseases when using product vending machines.

The present invention finds application in product vending machines dispensing products of any kind and in any state of matter, in particular solid or liquid food products, packaged or prepared at the moment on demand.

The present invention finds advantageous application in beverage vending machines dispensing hot or cold, packaged or so-called instant beverages, i.e., prepared on demand from liquid and/or powdered ingredients, to which the following disclosure will explicitly refer without losing generality.

The present invention may, however, find advantageous application in product vending machines dispensing products of a different kind, such as electronic products, gadgets, personal protective equipment, etc.

STATE OF THE ART

As known, in the field of vending machines, design is increasingly focusing on the development and adoption of technologies that increase interactivity between consumers and vending machines. For this reason, the Human-Machine Interfaces (HMI) of vending machines, e.g. dispensing instant beverages, are continuously evolving to allow consumers to interact with vending machines in an increasingly sophisticated way from different perspectives.

KR 102 134 903 B1 discloses an infection prevention certification kiosk comprising a housing with a hand inlet; a hand sanitizer dispenser installed in the hand inlet to automatically discharge a disinfectant solution when a user's hand is inserted in the hand inlet; a first body temperature measuring unit installed in the housing to measure body temperature through a thermal image of the user; a second body temperature measuring unit installed in the housing to measure the user body temperature in a non-contact manner; a certification issuance unit issuing infection prevention certification stickers for access and passage of multi-use facilities; and a control unit executing an output unit that outputs a warning message and an infection prevention authentication control program to control each unit. Therefore, it is possible to issue the infection prevention certification sticker in an unmanned manner, accurately measure body temperature with a double body temperature check, and share the authentication sticker, thereby smoothly controlling access of multi-use facilities.

CN 111 429 652 A discloses an intelligent vending machine with a respiratory disease screening function. The intelligent vending machine comprises a three-mode camera connected with an image/information processing module, and thermal imaging and depth picture acquisition are completed when a user uses automatic vending. The image/information processing module extracts the body temperature and the respiratory waveform of the user for respiratory disease screening, and transmits a screening result to a server and the mobile phone of the user. The body temperature and breath are detected and screened during use of the vending machine and abnormal information is sent to the user and related management departments as soon as possible. Infectious respiratory diseases can be prevented from spreading in public places to a certain extent and respiratory infection diseases of people in the public places can be screened while commodity purchasing of the user is not affected.

Marco Cristani et al., “The Visual Social Distancing Problem”, Arxiv.org, Cornell University Library, 201 Olin Library Cornell University Ithaca, NY 14853, (20200511) discloses a Visual Social Distancing (VSD) problem, defined as the automatic estimation of the inter-personal distance from an image, and the characterization of the related people aggregations. It is discussed how VSD relates with previous literature in Social Signal Processing and indicate which existing Computer Vision methods can be used to manage such problem.

US 2007/013493 A1 discloses a multi-functional monitor that utilizes a CCD camera to record an image of a head of a person. The image is then transmitted to an image processor (or a human-image recognition processor) for producing pixels of luminosity data of the image. Eventually, the pixel data are put into a central processing unit (CPU) wherein they are checked against a normal data for consistency. If they are not consistent or the person is determined to have an exceedingly high body temperature, the central processing unit (CPU) will control a driver to start a video recorder. Meanwhile, a relay will be activated to turn on a speaker and an LCD for warning the person and showing the body-temperature reading of the person. If the person continues to force in, the central processing unit (CPU) will notify a police authority through an automatic alarm system. It also warns the person with a flash light.

CN 111 311 799 A discloses a gate control system based on intelligent identification. The gate control system comprises a photoelectric detection switch, a video acquisition module, an image recognition module, an infrared body temperature detection module, a counting module, an information processor, a voice module and a gate device. When epidemic situations need to be prevented and controlled, the control system can intelligently carry out recognition and only allow people who correctly wear masks and have normal body temperatures to enter public places such as shopping malls, supermarkets, exhibition halls, scenic spots and entertainment venues; the number of people entering the public places is limited, so that the situation that people are too dense is avoided. Therefore, potential safety hazards of mutual infection between people are eliminated.

OBJECT AND SUMMARY OF THE INVENTION

The Applicant has observed that, in the current historical period, in which it is of vital importance to counter the spread of viruses such as Sars-CoV-2, also commonly
